New Federal Bill Targets State-by-State Supplement Laws — And the Industry Is Rallying Behind It
By Himiyer.com — March 23, 2026
What the Bill Does
In February 2026, Rep. Nick Langworthy (R-NY) introduced the Dietary Supplement Regulatory Uniformity Act. The legislation would reaffirm that the FDA — not individual state governments — holds primary authority over the regulation and marketing of dietary supplements under DSHEA. It would explicitly preempt state laws that restrict supplement sales in ways that go beyond federal requirements.
The Problem: A Growing State Patchwork
Over the past two years, a growing number of state legislatures have moved to regulate supplements independently. Bills imposing age restrictions or outright sales bans on supplements marketed for weight loss or muscle building are advancing in Michigan, Illinois, Massachusetts, New Jersey, and Hawaii, among others. Federal courts have largely upheld states' authority to impose these restrictions, and legal challenges from industry groups have failed to overturn them so far.
New York's Law as a Template
New York's law, effective April 2024, requires retailers and e-commerce businesses shipping into the state to verify that purchasers of weight-loss and muscle-building supplements are 18 or older. Other states are using the New York framework as a drafting model, creating a compliance maze for companies selling nationally. The Natural Products Association and the Council for Responsible Nutrition have both described the situation as unworkable at scale.
Industry Response
The NPA has launched a nationwide campaign to restore what it calls federal primacy over supplement regulation. The organization's VP of Government Affairs, Kyle Turk, framed the issue starkly: 2026 must be the year the supplement industry reasserts the primacy of DSHEA before the state-level fragmentation becomes permanent. The Langworthy bill is the primary legislative vehicle for that effort.
